Lawyers for the Army private formerly known as Bradley Manning and the American Civil Liberties Union filed the lawsuit Tuesday in Washington.

It seeks an order for the Defense Department to provide Manning with hormone therapy and other treatment for her gender identity condition at the U.S. Disciplinary Barracks at Fort Leavenworth, Kansas.

Army Lt. Col. Alayne Conway said she could not comment on pending litigation, per military policy.

Manning also seeks to be allowed to follow female grooming standards, including dress and hair length.

The 26-year-old former intelligence analyst is serving a 35-year sentence for sending classified documents to the WikiLeaks website. She changed her legal name in April after disclosing at her court-martial last year that she had been diagnosed with gender dysphoria.
